Australia’s first biosolids gasification facility

Logan Water has pioneered an Australian first biosolids gasification facility. The facility transforms sewage sludge (biosolids) into renewable energy and a sustainable product called biochar. Biochar can be used by the agricultural, composting, building and other industries.

The Loganholme Wastewater Treatment Plant (WWTP) operated a trial biosolids gasification facility during 2020. A permanent facility is under construction and will be completed in early to mid-2022.

Research into the performance of the trial facility showed that Logan Water’s solution:

• is heat-energy neutral
• reduces the amount of biosolids for disposal by around 90%
• eliminates about 95% of persistent organic pollutants (POPs) like polyfluoroalkyl substances (PFAS), and
• reduces about 63% of micro and nano-plastics in biosolids.

The process does not harm the environment and the resulting biochar contains bio-available nitrogen, phosphorus and potassium. Biochar also increases the water holding capacity of soil. This helps plants to germinate and grow in the hot Australian climate. 

Logan Water is progressing with the second stage of tenders from potential buyers of commercial quantities of biochar. The outcome of the tender process is expected in early to mid-2022.

Cedar Grove Environmental Centre

This award-winning centre is open daily from 5.30am to 6:30pm. Please note that the gates to the centre and carpark close at 6.30pm, please make sure you leave the Centre before this time.

Community members can visit the site to enjoy:

• a 2.5km walking track (loop) along the Logan River
• shaded seating and picnic tables
• parking, accessible toilets and drinking fountain
• viewing the Cedar Grove Landcare nursery and training facility.

Access is from Cedar Grove Road, and there is a public carpark at the end of the access road. Dogs on a leash are allowed but there is no access for motorbikes, horses, fishing or camping.

Apart from community facilities, the centre is home to Queensland’s first wastewater treatment plant to benefit the environment by producing record low nutrient levels in effluent and offsetting remaining nutrients through catchment restoration (visits to the treatment plant by arrangement only). The site master plan was developed with a Community Reference Group. Minutes of the meetings of this group are available from Logan Water on request.

Chambers Flat wastewater treatment plant

A new wastewater treatment facility is needed to service development in the Park Ridge, Logan Village and Yarrabilba areas in the coming years.

The planned facility currently known as the Chambers Flat wastewater treatment plant (WWTP) will ultimately be constructed on part of a 144 hectare site at Pleasant View Road, Chambers Flat.

Current status

Logan Water continues to progress planning for a future wastewater treatment plant (WWTP) at the Chambers Flat site. Construction of the WWTP is not expected to commence until after 2030, however design of a 20-25MW solar farm is underway for delivery in 2024-2025. The solar farm will support and power Logan City towards a Net Zero future.

Environmental areas and community recreation spaces will continue evolving through ongoing master planning sessions and regulatory approval processes. Site master planning activities include early screening, increasing habitat for wildlife including koalas and sustainability projects.

Community Reference Group

Due to a change in membership, Logan Water is calling for nominations to join the Chambers Flat Community Reference Group for the proposed Chambers Flat WWTP site. There are currently two positions available.

The purpose of the Community Reference Group is to:

• enhance communication between Council and community members affected by the project
• increase our understanding of community feedback about wastewater management and the development of the Chambers Flat WWTP and connecting trunk infrastructure
• maximise opportunities for the community and environment as part of the project. For example, the Community Reference Group is involved in helping to prepare a master plan for the site to accommodate the WWTP as well as community, environmental and / or other uses.

You can download the Chambers Flat WWTP Community Reference Group Terms of Reference (PDF 639 KB) and Chambers Flat WWTP Community Reference Group nomination form (PDF 240 KB).

Nominations close: Friday 29 September 2023 with the next Community Reference Group meeting to be held on Monday 30 October 2023.

The current members of the Chambers Flat Community Reference group are the following Chambers Flat residents:

• Brad O’Keefe
• Brendan Doman
• David Loch
• Kym Suthers 
• Sue Simpson
• Matthew Patterson
• Ted Austin

Loganholme Wastewater Treatment Plant upgrade

More than $100 million in major upgrade works are underway or recently completed at Loganholme Wastewater Treatment Plant (WWTP).

The upgrade will increase the plant’s capacity to process wastewater from our growing community, improve its environmental performance, and reduce operating costs for Council and customers.

On site, Logan Water is constructing Australia’s first permanent biosolids gasification facility. The facility will transform biosolids (sludge from wastewater) into renewable energy and a safe, environmentally friendly product called biochar.

A 1000kw solar array is now operating to help power treatment operations and reduce Council’s carbon footprint. The array includes around 3,000 solar panels.

The plant’s main treatment process is receiving a major overhaul. This includes construction of a modern membrane bioreactor treatment facility covering 3.500 square metres. The technology will increase the plant’s treatment capacity from 45 million litres per day to 67 million litres per day and will service an additional 100,000 people. It will complement the existing conventional treatment process at the WWTP and enable the transfer of flows from the Beenleigh WWTP (which will ultimately be de-commissioned).

The existing pump station at the WWTP has been upgraded with new pumps, valves and pipework to manage incoming wastewater flows more efficiently and enhance safety for operators.
